Bifidobacterium Breve and Ticarcillin , Clavulanate

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIBIOTIC DRUGS

Why this applies to Ticarcillin , Clavulanate

Ticarcillin , Clavulanate falls under ANTIBIOTIC DRUGS — the group Bifidobacterium Breve interacts with.

Theoretically, taking Bifidobacterium breve with antibiotic drugs might decrease the effectiveness of B. breve.
Since B. breve preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. breve preparations by at least 2 hours.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: ticarcillin with clavulanate (Timentin) is a powerful antibiotic given to fight bacterial infections. It doesn't tell good and bad bacteria apart, so when you take it, it can also wipe out a good chunk of the friendly Bifidobacterium breve organisms in your probiotic. This doesn't make your antibiotic dangerous or less effective. It just means your probiotic may not do much while the two are taken at the same time.

To get the most out of your probiotic, a good habit is to space it at least 2 hours apart from your antibiotic dose. Keep in mind this is a theoretical concern based on how these products work, not a serious safety risk. If you have questions about timing, your pharmacist can help you sort it out.

From our pharmacist’s overview on the Ticarcillin , Clavulanate page

“Anyone receiving ticarcillin and clavulanate (Timentin) should treat this list with real care, and the place to start is the kidneys. The two major-rated entries, Siberian cocklebur and asarabacca, can each damage kidney function on their own, and stacking that harm on top of a kidney-stressing situation is the risk I would rule out be…”
